Vocal cord issues forced the singer to postpone dates earlier this year, as well.
Adele has just wrapped up touring the United Kingdom and was preparing to kick off her U.S. tour Friday in Atlantic City, N.J., when her illness reappeared, Columbia Records said Tuesday.
The Grammy Award winner has been advised by doctors she'll need an extended rest period to recuperate properly.
Further details regarding the canceled dates are to follow soon, her label said.
"singing is literally my life, its my hobbie, my love, my freedom and now my job. I have absolutely no choice but to recuperate properly and fully, or i risk damaging my voice forever," Adele said in a message posted on her Web site. "you know how much this upsets me, how seriously i take it and how truly devastated and annoyed i am by this. wanting to do something so bad and not being able to is the most frustrating thing as im sure you know!"
She went on to say her voice is weak and she needs to build it back up. Once she does, she said, "i will be back and im gonna smash the ball out the park once im touring again."
She also apologized to her fans for not only not being able to perform for them but disrupting their plans.
